Fair point and a good distinction to make. I should rather have said "software development ideology driven development" since as you say, all decisions ultimately stem from value judgements.

I'm certainly OK with software development decisions being driven by an ideology of "this code shouldn't be able to injure anyone", just not with it being driven by an ideology of "everything must be an object" or "tests must always be developed before code, and any code which passes the tests is OK" or "code which uses the 'unsafe' keyword is bad".
